Water is the main staple. If you can control that, you are partially set.
With all of this IRAN deal boiling up, I sure hope the SHTF don't happen till later when it cools off some. Water will go a lot quicker down here in Texas in this kind of HEAT!
I will make a stop over by the Auto parts place this evening for a couple of 12V FANS. I have plenty of 12V power with the solar panels and battery array.
